Visual memory for feature bindings: The disruptive effect of responding to new perceptual input

In the current study, we examined how short-term memory for location–identity feature bindings is influenced by subsequent cognitive and perceptual processing demands. Previous work has shown that memory performance for feature bindings can be disrupted by the presentation of subsequent visual information, particularly when this information is similar to that held in memory. The present study demonstrates that memory performance for feature bindings can be profoundly disrupted by also requiring a response to visual information presented subsequent to the visual memory array. Across five experiments, memory for a location–identity binding was substantially impaired following a localization response to a following item that matched the location but mismatched the identity of the memory target. The results point to an important role for action in the episodic integration processes that control short-term visual memory performance.     

Event justice and social entity justice: A cross-lagged analysis

IntroductionThe life of organizations is punctuated by a wide range of managerial decisions (e.g., hiring and selection procedure, performance appraisal, new working methods). Facing such events, employees evaluate the fairness of the situation experienced (event justice). They can also examine the fairness demonstrated by a specific entity, such as the organization or the supervisor (social entity justice). So far, little is known about how justice judgments about events vs. entities are related to each other, especially in a context of organizational change.ObjectiveBuilding on decision-making and organizational justice literature, we investigate the directionality of the causal relationships between event justice and social entity justice within a context of organizational change in a Belgian company (a significant reorganization at the level of the organization chart resulting in different changes for employees).MethodsWe used two samples (team leaders and executives) and realized a cross-lagged panel analysis with two measurement times.ResultsThe study shows that, in both samples, employees’ fairness perceptions about their organization (social entity justice) influence their interpretation of the fairness of subsequent events involving the organization (event justice).ConclusionBuilding and fostering a climate of justice is therefore of primary importance to organizations, since global fairness perceptions about the organization may help employees to perceive a specific event, such as an organizational change, as being fair.     

Examining the relationships between self‐efficacy,task‐relevant attentional control,and task performance: Evidence from event‐related brain potentials

Self‐efficacy (SE) is a modifiable psychosocial factor related to individuals’ beliefs in their capabilities to successfully complete courses of action and has been shown to be positively associated with task performance. The authors hypothesized that one means through which SE is related with improved performance is through enhanced task‐relevant attentional control during task execution. To assess this hypothesis, we examined the relationships between SE and behavioural and neural indices of task performance and task‐relevant attentional control for 76 young adults during the completion of a flanker task. Results showed that greater SE was associated with greater response accuracy and P3b amplitude across task conditions, and faster RT under more difficult task conditions. Additionally, P3b amplitude was found to mediate the relationship between SE and task performance in the difficult condition. These findings suggest that greater attentional allocation to task‐relevant processes, including monitoring stimulus‐response relationships and focusing attention on working memory operations, may help explain the association between SE and improved task performance.     

Comprehension Models of Audiovisual Discourse Processing

Comprehension is integral to enjoyment of media narratives, yet our understanding of how viewers create the situation models that underlie comprehension is limited. This study utilizes two models of comprehension that had previously been tested with factual texts/videos to predict viewers' recall of entertainment media. Across five television/film clips, the landscape model explained at least 29% of the variance in recall. A dual coding version that assumed separate verbal and visual representations of the story significantly improved the model fit in four of the clips, accounting for an additional 15–29% of the variance. The dimensions of the event‐indexing model (time, space, protagonist, causality, and intentionality) significantly moderated the relationship between the dual coding model and participant recall in all clips.     

Walking through doorways causes forgetting: Further explorations

Previous research using virtual environments has revealed a location-updating effect in which there is a decline in memory when people move from one location to another. Here we assess whether this effect reflects the influence of the experienced context, in terms of the degree of immersion of a person in an environment, as suggested by some work in spatial cognition, or by a shift in context. In Experiment 1, the degree of immersion was reduced by using smaller displays. In comparison, in Experiment 2 an actual, rather than a virtual, environment was used, to maximize immersion. Location-updating effects were observed under both of these conditions. In Experiment 3, the original encoding context was reinstated by having a person return to the original room in which objects were first encoded. However, inconsistent with an encoding specificity account, memory did not improve by reinstating this context. Finally, we did a further analysis of the results of this and previous experiments to assess the differential influence of foregrounding and retrieval interference. Overall, these data are interpreted in terms of the event horizon model of event cognition and memory.     

The reminiscence bump in older adults' life story transitions

Older adults' memories of events that occurred in adolescence and early adulthood are over-represented compared to other lifetime periods. Prior research on this reminiscence bump has focused on qualities of individual memories. The present study used a novel interview method to examine the potential role played by mental representations of extended lifetime periods. Older adults provided oral life stories, and they divided their transcribed narratives into “chapters”. Participants' ages at chapter beginnings and endings showed pronounced reminiscence bumps. The results are consistent with the idea that personal episodes occurring near the boundaries of extended lifetime periods receive preferential processing that enhances long-term memory.     

The neural basis of updating: Distinguishing substitution processes from other concurrent processes

Sörqvist, P. & Sætrevik, B. (2010). The neural basis of updating: Distinguishing substitution processes from other concurrent processes. Scandinavian Journal of Psychology, 51, 357–362. Most previous studies of updating processes have not been able to contrast processes of substituting items in memory with other concurrent processes. In the present investigation, we used a new task called “number updating” and an fMRI protocol to contrast the activation of trials that require item substitution (adding a new item to the working memory representation and suppressing an old item) with trials that involve no substitution (discarding the new item). Trials that require item substitution activated the dorsolateral prefrontal cortex, the posterior medial frontal cortex and the parietal lobes, areas typically seen activated for working memory tasks in general. Trials that do not require substitution activated the anterior medial frontal cortex. Studies examining executive functions have associated this area with cognitive conflict, and may represent suppression of the substitution processes.     

Exploring Temporal Progression of Events Using Eye Tracking

This study investigates the representation of the temporal progression of events by means of the causal change in a patient. Subjects were asked to verify the relationship between adjectives denoting a source and resulting feature of a patient. The features were presented either chronologically or inversely to a primed event context given by a verb (to cut: long–short vs. short–long). Effects on response time and on eye movement data show that the relationship between features presented chronologically is verified more easily than that between features presented inversely. Post hoc, however, we found that the effects of temporal order occurred only when subjects read the features more than once. Then, the relationship between the features is matched with the causal change implied by the event context (contextual strategy). When subjects read the features only once, subjects respond to the relationship between the features without taking into account the event context.
